Light emission module, light emission module manufacturing method, and lamp unit

In a light emission module (40), a light wavelength conversion ceramic (52) is formed in a sheet shape which converts the wavelength of the light emitted from a semiconductor light emission element (48) when emitting the light. The light wavelength conversion ceramic (52) has a tapered plane (52a) w...

More Information
Summary:In a light emission module (40), a light wavelength conversion ceramic (52) is formed in a sheet shape which converts the wavelength of the light emitted from a semiconductor light emission element (48) when emitting the light. The light wavelength conversion ceramic (52) has a tapered plane (52a) which is inclined to approach the semiconductor light emission element (48) toward the brim portion. The light wavelength conversion ceramic (52) is transparent and is arranged so that the light emission wavelength band after the conversion has an all ray permeability of 40 % or above.
